Hydrothermal construction of flower-like g-C3N4/NiZnAl-LDH S-scheme heterojunction with oxygen vacancies for enhanced visible-light triggered photocatalytic performance

Construction of NiCo-LDH/g-C3N4 heterojunctions as efficient photocatalysts for enhanced degradation of tetracycline hydrochloride and hydrogen evolution

“…In addition, the ESR detection technique was used to further investigate that the active components were implemented to further certify the existence of active species of OH and O 2 À in the photocatalytic degradation process. 28 As shown in Fig. 9 radicals could be generated in the photocatalytic process over the LDH12/CN sample, and this is in agreement with the results of quenching experiments.…”

“…In addition, the ESR detection technique was used to further investigate that the active components were implemented to further certify the existence of active species of ˙OH and ˙O 2 − in the photocatalytic degradation process. 28 As shown in Fig. 9(b) and (c), no obvious signals of DMPO–˙OH and DMPO–˙O 2 − adducts can be detected under dark conditions.…”

“…Pristine CN and all the prepared LDH/CN nanocomposites have one strong peak for the (002) plane at 27.81 and a weak peak for the (100) plane at 12.91, which represented the planar stacking structure of the aromatics with typical interlayer packing. 28 The characteristic peaks of pure LDH were located at 2y = 11.01, 20.91, 34.21, 37.81, 44.51 and 60.11corresponding to the (003), (006), (012), (015), (018), and (110) planes. 29 Characteristic diffraction peaks representing the CN and LDH were evidently shown in the XRD spectra of LDH/CN samples, which proves the successful coupling of the two catalysts.…”

CeMnO3 Nanoparticle-Decorated g-C3N4 Nanosheets as Z-Scheme Heterostructures for Efficient Photocatalytic Degradation of Dyes

“…When the linear section of these was extrapolated to the potential axis, the intersections determined the flat band potentials as 0.37 and −0.95 V (vs Ag/AgCl, pH = 13.6), which could be converted to 0.18 and −1.15 V (vs NHE, pH = 0), for CMO nanoparticles and g-CN nanosheets, respectively. The flat-band potentials can be approximately considered to be conduction band edges. , The calculated CB and VB edges for CMO nanoparticles were determined to be 0.18 and 1.78 eV, respectively. The CB and VB potentials of g-CN were established at −1.15 and 1.56 eV, respectively, which is nearly equal to the previously published reports .…”
